Environment & Ecology Current Affairs - 2026-04-19

Background: Wetlands are critical ecosystems that act as carbon sinks and natural water filters. India has seen a decline in wetland health due to urbanization. Current Context: The Ministry of Environment, Forest and Climate Change has launched the 'National Wetland Restoration Mission' in April 2026 to revive 500 degraded wetlands across the country. Impact: This initiative aims to enhance biodiversity, improve groundwater recharge, and mitigate flood risks in urban areas. It aligns with India's Nationally Determined Contributions (NDCs) to combat climate change and promote sustainable water management practices.

Background: The Himalayas, often called the 'Third Pole', are experiencing rapid glacial retreat due to global warming. This threatens the water security of millions downstream. Current Context: In April 2026, the Geological Survey of India (GSI) deployed advanced satellite-based sensors to monitor glacial melt rates in real-time across the Himalayan range. Impact: This data-driven approach will provide early warnings for Glacial Lake Outburst Floods (GLOFs). It enables better disaster management planning and helps policymakers formulate long-term strategies to protect the fragile mountain ecosystem from the adverse impacts of climate change.
